Title: Improvements in or relating to vacuum braking systems
Inventor: BALLARD DONALD HENRY
IPC: B60T13/24
Filed: 1958-10-16
Abstract: 913,304. Fluid-pressure brakes. CLAYTON DEWANDRE CO. Ltd. Jan. 18, 1960 [Oct. 16, 1958], No. 33072/58. Class 103 (1). A fluid pressure - operated braking mechanism has a servo cylinder 1 extended at one end to constitute a vacuum reservoir 3, a pedal-actuated valve disposed at one end of cylinder 1, a master cylinder 4 supported on the rear end 5 of cylinder 1 and extending at least part way into cylinder 1, and means extending coaxially of the cylinder to transmit the manual effort applied to the pedal and the output of the servomotor to the master cylinder. The master cylinder 4 is connected to, or integral with, the end 5 of cylinder 1 to which is connected a housing 18 containing a liner 19 housing a thrust member 23 having a valve seat 24 normally engaged by a spring-pressed valve disc 25; a control element 34 slidable in member 23 is connected via a rod 35 to a plunger 29 extending within master cylinder piston 11. A series of radiallyextending levers 32 pivoted to plates 33 welded to liner 19, engage abutments 2a on piston 2 and the thrust member 23. In the release position shown, vacuum from reservoir 3 is communicated to the left-hand side of piston 2 via ports 36, element 34, ports 26, 27 and chamber 28, the master cylinder chambers 7, 8 being connected to reservoirs 13, 13a through valves 14, 14a. On braking, brake pedal rod 21 moves member 23 through socketed member 20, to first seat disc valve 25 on element 34 and then move seat 24 from valve 25 to connect the left-hand servo chamber with atmosphere via port 22, past seat 24, ports 26, 27 and chamber 28. The piston 2 then moves to force piston 11 into chamber 7 via levers 32, plates 33 and plunger 29. The piston 2 acts through levers 32 on member 23 to transmit " feel " to the pedal. When pedal movement ceases, piston 2 and liner 19 continue to move with element 34 until disc valve 25 engages seat 24 and element 34. When the force on the pedal is removed, spring 37 acting on element 34 via rod 35 and on member 23 via element 39 withdraws element 34 from valve 25 to re-establish communication between opposite of piston 2 which is returned to its release position by spring 41. On failure of the vacuum, effort from the pedal is transmitted to master cylinder piston 11 via members 20, 23, levers 32, plates 33 and plunger 29.

Abstract: 917,463. Contacting gases with liquids. GESELLSCHAFT DER L. VON ROLL'- SCHEN EISENWERKE A.G. Sept. 27, 1960 [Sept. 29, 1959; Nov. 13, 1959; May 18, 1960], No. 33208/60. Class 55 (2). Gas is contacted with a liquid, for example, to wash it, by passing it through the narrow passage 81, Fig. 6, between two convergently sloping surfaces 84, 89, at least one of which is movable to vary the size of the passage 81 and at least one of which is supplied with the liquid. As shown, water, which may be recycled and thus contain a proportion of dust, is supplied to chamber 83 and emerges beneath baffle 93 to flow down surface 89 and become intimately mixed with dust-laden gas passed downwardly from an inlet 80. Water is also supplied to a chamber 85 and flows down the annular space between surfaces 84 and 86a, the surface 84 being formed on a conical member which may be moved longitudinally in the direction C-C to vary the passage 81. The movement of surface 84 may be automatic in dependence on the volume of gas flow. The gas passes away through the centre of the movable conical member, the dust-laden water passing away through drain 97. In a modification, Fig. 5, the fixed surface 61 is supplied with liquid from chamber 66, whilst the movable surface 62 is supplied from chamber 67. The liquid may be tangentially supplied to the chambers to prevent deposit of dust in the chambers and pipes. In further modifications the apparatus is of rectangular crosssection and both convergent surfaces may be movable.

Title: Improvements in three phase generating systems
IPC: H02J7/14
Filed: 1967-07-20
Abstract: 1,128,735. Generating systems for vehicles. ROBERT BOSCH G.m.b.H. 20 July, 1967 [21 July, 1966], No. 33296/67. Heading H2H. A three-phase generating system for road vehicles and the like comprises means for changing the phase windings of the three-phase generator from star to delta connection when the speed of the generator or its output current exceeds a predetermined value. A three-phase generator 10 driven at widely varying speeds supplies a load circuit 24, 25 by way of a rectifier 23, the generator field winding 14 being energized from the generator output by way of an auxiliary rectifier 26 and a voltage regulator 27. The connections of the generator output windings 11, 12, 13 are controlled by a relay 15, the contacts of which are shown in the positions wherein the generator is stationary or rotating at slow speeds and delivering a low output current. In these positions the windings 11, 12, 13 are in star connection. As the load taken by the output circuit increases the output of the current transformer 28 and rectifier 29 increases until the breakdown point of a Zener diode 35 is reached whereupon a transistor 32 conducts to energize the relay 15 thus changing the contact positions to connect the windings 11, 12, 13 in delta. Contact 20 of the relay 15 opens before, and closes after, contacts 17-19 so that these latter contacts operate under no-load conditions. The operation of relay 15 may be made responsive only to the generator speed. In the case of generators having a small current output the current transformer 28 may be dispensed with and the Zener diode 35 and transistor 32 made responsive to the voltage drop across a resistor 37. Furthermore a resistor may be placed in series with the variable resistor 34 to obtain switching hysteresis.
